We have a local office network running through Windows Small Business Server 2003. All computers connected to the LAN work fine, and are able to connect to the domain controller and network shares using their hostnames. (ie. I can mount \\myfileserver\myshare).
We also have a wireless router, which is connected directly to the office network. Computers connected to the wireless can use the internet, and can connect to the fileservers at \\192.168.x.x\myshare, but not at \\myfileserver\myshare. They also can't connect to the exchange server by name, or anything else.
What could be causing the names not to resolve over the wireless network?
